PFAnalytics.trackAppOpenedWithLaunchOptions中的錯誤（launchOptions，塊：無）

Question

我試圖將Parse導入到我的Swift應用程序中，並且每次我添加// Register for Push Notifications時，我都會收到一條錯誤消息，提示“ PFAnalytics.Type”沒有名為“ trackAppOpenedWithLaunchOptions”的成員，我從字面上復制並粘貼了部分代碼解析網站，不知道如何解決

// Register for Push Notitications
    if application.applicationState != UIApplicationState.Background  {
        // Track an app open here if we launch with a push, unless
        // "content_available" was used to trigger a background push        (introduced in iOS 7).
        // In that case, we skip tracking here to avoid double   counting the app-open.

        let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
        let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
        var noPushPayload = false;
        if let options = launchOptions {
            noPushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil;
        }
        if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) {
            PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions, block: nil)
        }
    }
    if application.respondsToSelector("registerUserNotificationSettings:") {
        let userNotificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound
        let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    } else {
        let types = UIRemoteNotificationType.Badge | UIRemoteNotificationType.Alert | UIRemoteNotificationType.Sound
        application.registerForRemoteNotificationTypes(types)
    }

由於您將nil傳遞給該塊，因此請替換以下行：

PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions, block: nil)

與此：

PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)

如果您需要在后台執行此操作，請使用以下行：

PFAnalytics.trackAppOpenedWithLaunchOptionsInBackground(launchOptions, block: nil)
